As illustrated in FIG. 1, a stand 100 for a display apparatus of an embodiment is provided to be mounted to a fixing object (not shown). The fixing object may be a recreational vehicle, a ceiling, a wall, etc.. The stand 100 includes a fixing plate 10 fixedly connected to the fixing object, a mounting plate 50 for mounting the display apparatus, and a rotating arm 30 rotatably connected between the fixing plate 10 and the mounting plate 50. Specifically, one surface of the fixing plate 10 is attached to the fixing object, and an opposite surface of the fixing plate 10 is rotatably connected to one end of the rotating arm 30. An opposite end of the rotating arm 30 is rotatably connected to the mounting plate 50. The fixing plate 10, the rotating arm 30, and the mounting plate 50 are connected in sequence. Therefore, the stand 100 is switchable between a folded state and an unfolded state. When the stand 100 is rotated to be the folded state, the stand 100 is capable of being operated to be a locked state. In this state, the stand 100 cannot rotate. After the stand 100 is operated to unlock from the locked state, the stand 100 is capable of rotating to the unfolded state from the folded state.

The fixing plate 10 may be a rectangular plate. Several fixing holes 13 are uniformly defined at different positions of the fixing plate 10, so that the fixing plate 10 is fixedly mounted to the fixing object by cooperations of the fixing holes 13 and screws. A plurality of engaging blocks 15 are disposed on the middle of the fixing plate 10. The engaging blocks 15 are arranged along a width direction of the fixed plate 10. Referring to FIG. 5, when the stand 100 is in the folded state, a top surface of the engaging block 15 is contacted with a sidewall of the rotating arm 30, thereby preventing the rotating arm 30 from over-rotating towards the fixing plate 10. Thereby ensure that the display apparatus is parallel to the fixing plate 10. When the fixing plate 10 is mounted to a horizontal fixing object, the display apparatus is held to be horizontal, in order to improve the use experience. When the rotating arm 30 is rotated to be parallel to the fixing plate 10, the thickness of the engaging block 15 is a distance between the rotating arm 30 and the fixing plate 10.

As illustrated in FIG. 1, in this embodiment, two sets of mounting pieces 17 are vertically extended from a top wall of the fixing plate 10. The two sets of mounting pieces 17 are respectively disposed at opposite ends along a length direction of the top wall of the fixing plate 10. Each set of mounting pieces 17 comprises a first mounting piece and a second mounting piece, which are arranged at intervals along the length direction of the fixing plate 10. A rotating space 173 is defined between the first and second mounting pieces of each set of mounting pieces 17. The rotating arm 30 is connected to the two mounting pieces of each set of mounting pieces 17 with two ends of the rotating arm 30 received in the rotating space 173. It can be understood that the number of sets of mounting pieces 17 is not limited and is depended on actual needs.

As illustrated in FIG. 1, and FIG. 4, a locking apparatus 11 is disposed at one end of the top wall of the fixing plate 10. The locking apparatus 11 may include at least one base 114 and a locking member 110 and at least one elastic member 1143. The locking member is attached to the at least one base 114 and movable relative to the at least one base 114. The locking member 110 includes a connecting rod 113, a first locking rod 111 and a second locking rod 112. An operating member 116 is coupled to the locking member 110. In this embodiment, the operating member 116 is a pull rope which is attached to the connecting rod 113. The first locking rod 111 and the second locking rod 112 are connected with the connecting rod 113 and vertically extended from opposite ends of the connecting rod 113. Specifically, the locking member 110 is disposed to be parallel to the fixing plate 10, while the first locking rod 111 and the second locking rod 112 are spaced with each other and disposed between the engaging blocks 15 and the connecting rod 113. The first locking rod 111, the connecting rod 113, and the second locking rod 112 are connected in sequence. The first locking rod 111 and the second locking rod 112 are relatively parallel and arranged at intervals, thereby forming a U-shaped groove 117. Two sets of mounting pieces 17 are spaced at opposite sides of the engaging blocks 15 with one set of mounting pieces 17 being received in the U-shaped groove 117. The mounting pieces 17 may be disposed to be parallel to the connecting rod 113. The mounting pieces 17 may limit a farthest position of the movement of the moving member towards the engaging blocks 15.

As illustrated in FIG. 4, in this embodiment, there are two bases 114 respectively corresponding to the first locking rod 111 and the second locking rod 112. Each base 114 includes a first wall 1141 located near the connecting rod 113, a second wall 1142 opposite to the first wall 1141. In this embodiment, limiting holes (not shown in the figures) are correspondingly provided in the first wall 1141 and the second wall 1142, so that the first locking rod 111 or the second locking rod 112 respectively pass through the limiting holes of the corresponding first wall 1141. Thus, the first locking rod 111 and the second locking rod 112 are slidably attached to the bases 114. The number of the elastic member 1143 is same as the base 114. The elastic member 1143 and a pushing plate 1144 are located between the first wall 1141 and the second wall 1142 of each base 114. Both of the elastic member 1143 and the pushing plate 1144 are sleeved on the first locking rod 111 or the second locking rod 112. One end (beside the connecting rod 113) of the elastic member 1143 is fixedly connected to the first wall 1141, and the other end is fixedly connected to the pushing plate 1144. The pushing plates 1144 are fixedly connected to the first locking rod 111 and the second locking rod 112. The elastic members 1143 are engaged with the first walls 1141 and the pushing plates 1144 so as to provide a restoring force onto the first locking rod 111 and the second locking rod 112.

The operating principles of locking apparatus 11 is explained in the following.

When unlock the locking apparatus 11 from the locking state, the operating member 116 is operated by a user, which makes the locking apparatus 11 to move relative to the fixing plate 10. The first locking rod 111 and the second locking rod 112 are pulled by the operating member 116 to slide, so as to drive the pushing plates 1144 to move together towards a direction away from the engaging block 15. At this time, one end of the elastic members 1143 connected to the pushing plates 1144 moves with the pushing plates 1144, and the other end is fixedly connected to the first wall 1141, so that the elastic members 1143 are pushed by the pushing plates 1144 and move towards the first wall 1141, thereby the elastic members 1143 are compressed by the pushing plates 1144 and the first walls 1141. The locking apparatus 11 is thus in the unlocked state. When the operating member 116 is released from the user, the locking apparatus 11 is driven to move back until the pushing plates 1144 are resisted by the second walls 1142 by the restoring force from the elastic members 1143. The locking apparatus 11 returns to its original position, reaching the locking state.

As illustrated in FIG. 1, and FIG. 2, The rotating arm 30 coupled between the fixing plate 10 and the mounting plate 50 includes a front arm 31 coupled to the mounting plate 50, a rear arm 32 coupled to the fixing plate, and a transverse rod 33 connecting the front arm 31 and the rear arm 32. The rear arm 32 is a dual-arm structure, which includes a first support arm 321 and a second support arm 322 parallel to the first support arm 321. Each of the first support arm 321 and the second support arm 322 has an end accommodated between a corresponding set of mounting pieces 17. In a set of mounting pieces 17, a first through hole (not shown in the figure) is defined through the side peripheral wall of one of the mounting pieces 17, and a second through hole 171 corresponding to the first through hole is defined through the other mounting piece 17. The first support arm 321 is located between the two mounting pieces 17 in the first set of mounting pieces 17, and the second support arm 322 is located between the two mounting pieces 17 in the second set of mounting pieces 17. Two first shaft pins 175 pass through the second through holes 171 of a set of mounting pieces 17 and the first through holes of the corresponding support arms 321 and 322, respectively, so that the mounting pieces 17 and the support arms 321 and 322 are rotatably connected together. Thus, the rotating arm 30 may rotate relative to the fixing plate 10. The other ends of the first support arm 321 and the second support arm 322 are penetrated to form a third through hole (not shown in the figure). The third through hole is defined at each of the other ends of the first support arm 321 and the second support arm 322. The transverse rod 33 passes through the third through hole, so that the transverse rod 33 is rotatably connected to the first support arm 321 and the second support arm 322. The front arm 31 is parallel to the first support arm 321 and the second support arm 322 with one end of the front arm 31 being connected to the middle of the transverse rod 33. The front arm 31 may rotate about the transverse rod 33. A receiving space 35 is defined between the first support arm 321 and the second support arm 322 for accommodating the front arm 31 therein. Specifically, the front arm 31 is a single arm structure, and the front arm 31 and the rear arm 32 are telescopiform structure. The front arm 31 may be stacked in the receiving space 35, increasing the stability of the overall structure and improving its reliability. In addition, the front arm 31 and the rear arm 32 of the stand 100 may be folded, thereby improving portability.

In this embodiment, at least one wire clamp 37 is provided on at least one of the first support arm 321, the second support arm 322, and the front arm 31. The wire clamp 37 is used for binding electric wires with the first support arm 321, the second support arm 322, and/or the front arm 31, so as to prevent the electric wires routing and twine of the display apparatus, making it more convenient.

As illustrated in FIG. 2, and FIG. 3, the mounting plate 50 includes a back plate 51 on which the display apparatus is directly fixed, a connecting seat 55 connected to the front arm 31, and an adjustable seat 53 coupled between the connecting seat 55 and the back plate 51. One end of the front arm 31 away from the transverse rod 33 is rotatably connected to the adjustable seat 55. The connecting seat 55 includes a main body 551 parallel to the fixing plate 10, and two clamps 553 are extended vertically from both ends of the main body 551 towards the side close to the rotating arm 30. A fourth through hole 5531 is defined in the two clamp 553, and one end of the front arm 31 is clamped between the two clamps 553. The second shaft pin 5533 passes through the fourth through hole 5531 of the clamp 553 and a fifth through hole of the front arm 31, so that the mounting plate 50 and the rotating arm 30 can be rotatably connected together. At least one of the two clamps 553 extends vertically outward from a lowest position to form a locking element 555, which is used to cooperate with the locking apparatus 11 to lock the stand 100 and prevent shaking.

One end of the adjustable seat 53 is connected to the connecting seat 55 through a connecting member, such as a screw, and the other end of the adjustable seat 53 is extended towards the side close to the rotating arm 33. A set of waist holes 531 is defined in the other end of the adjustable seat 53. The waist holes 531 are arc-shaped long holes. A waist hole screw 533 passes through the waist holes 531 and the connecting seat 55, thereby the adjustable seat 53 and the connecting seat 55 are connected together. The waist hole screw 533 is slidable in the circular-arc-shaped waist hole 531, so that the adjustable seat 53 is driven to rotate slightly up or down relative to the connecting seat 55, thereby achieving viewing angles of the display apparatus.

A protrusion 511 is obliquely extended downward from a side of the back plate 51 which is near the waist hole 531. A notch 535 is defined at an upper end of the waist hole 531 of the adjustable seat 53 corresponding to the protrusion 511. When the back plate 51 contacts the adjustable seat 53, the protrusion 511 is inserted into the notch 535, so that one end of the back plate 51 are connected to the adjustable seat 53. The above is a connection method between the back plate 51 and the adjustable seat 53, which is used to enhance the stability of the back plate 51 connection and improve the load-bearing capacity.

The folding and locking process of the stand 100 is explained in the following.

As illustrated in FIG. 1, the mounting plate 50 is parallel to the fixing plate 10, and the rotating arm 30 is located in a plane which is perpendicular to both the fixing plate 10 and the mounting plate 50. The stand 100 is in a fully unfolded state. When folding the display stand 100, firstly, the user push the display apparatus to take the mounting plate 50 to rotate. The connecting seat 55 then rotates relative to the rotating arm 30 until the mounting plate 50 is parallel to the front arm 31 of the rotating arm 30. The transverse rod 33 is thus pushed to cause the transverse rod 33 to drive the front arm 31 to rotate until the front arm 31 is received in the receiving space 35. Then, the user operates the operating member 116, causing the locking apparatus 11 to move away its original location towards the side close to the operating member 116. While holding the operating member 116, rotate the rear arm 32 towards one of the two sides until the front arm 31 contacts the engaging block 15, the locking element 555 is located below the position before the first locking rod 111 and the second locking rod 112 move. When the operating member 116 is released, the locking apparatus 11 is returned to an original position by the restoring force of the elastic member 1143. so as to drive the locking device 11 return to its original position. Thus, the locking element 555 is locked by the first locking rod 111 and the second locking rod 112. As illustrated in FIG. 5, at this time, the fixing plate 10, the rotating arm 30, and the mounting plate 50 are parallel to each other, the folding locking process, such as a self-locking process is completed. The front arm 31 and the rear arm 32 are stacked in a same plane with the front arm 31 being protrudes from the rear arm 32. At this time, the mounting plate 50 is parallel to the fixing plate 10.

The stand 100 of this embodiment comprises a dual-rod locking structure having a first locking rod 111 and a second locking rod 112. A larger locking range and more stable locking is achieved, when applied to scenarios such as recreational vehicles, the stand of this embodiment can provide users with a better use experience.
